What Types of Fertilizers Are There? A Detailed Guide to Common Fertilizer Classification

These include ammonium phosphate fertilizers, macronutrient water-soluble fertilizers, secondary element fertilizers, biological fertilizers, organic fertilizers, and multi-dimensional field-energy concentrated organic fertilizer.

When storing fertilizers, pay attention to:

1. Prevent moisture regain and deterioration

For example, ammonium bicarbonate easily absorbs moisture, causing nitrogen volatilization loss; ammonium nitrate is highly hygroscopic and easily cakes and deliquesces; calcium cyanamide and superphosphate easily cake after absorbing moisture, affecting application effectiveness. Therefore, these chemical fertilizers should be stored in a dry, cool place. In particular, ammonium bicarbonate must be sealed tightly when stored to avoid contact with air.

2. Prevent fire and avoid sunlight

After nitrogen fertilizers are exposed to sunlight or high humidity, nitrogen volatilization loss accelerates; ammonium nitrate decomposes to release oxygen at high temperatures and can burn when it meets flammable materials. Never strike caked ammonium nitrate with an iron hammer, as this may cause an explosion. When storing nitrogen fertilizers, avoid sunlight and strictly prohibit smoking and open flames. Do not stack them together with diesel, kerosene, firewood, grass, or similar items.

3. Prevent volatilization loss

Ammonia water and ammonium bicarbonate very easily volatilize and are lost, so they must be sealed during storage. Nitrogen fertilizers and superphosphate must never be stacked together with alkaline substances (lime, plant ash, etc.), to prevent volatilization loss of nitrogen fertilizers and reduce the fertilizer efficiency of phosphate fertilizers.

4. Prevent corrosion and toxicity

Superphosphate is corrosive, so prevent contact with skin and metal tools; ammonia water is strongly corrosive to copper and iron, so it should be stored in ceramic, plastic, or wooden containers. In addition, chemical fertilizers must not be stacked together with seeds, and fertilizer bags should not be used to hold seeds, so as not to affect seed germination.

At present, there are many types of fertilizers and many manufacturers on the market. When purchasing, pay attention to distinguishing genuine from fake, and do not be misled by exaggerated claims about effects and functions.
